Transition pairings which started in September and ended in October were built to minimize the number of segments on either side of the transition. Due to the exceptional nature of these pairings, there are one-time impacts to pay and credit time which are detailed by pre-merger workgroup in the One United publication that was released today.
If you flew a pairing that departed in the September 2018 bid month and completed in October 2018 and it appears that you are missing any credit for that pairing in October, contact Flight Attendant Crew Pay Support at 1-800-FLT-LINE, options 5,1,2.
